5 Electron Shells and the Bohr Model Note that there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has. In all electrically neutral atoms, the number of electrons is the same as the number of protons. Thus, each element, at least when electrically neutral, has a characteristic number of electrons equal to its atomic number. In 1913, Danish scientist Niels Bohr (1885–1962) developed an ear
